(Test Method)Standard Test Method for Determining the Peak Force-to-Actuate a Mechanical Pump Dispenser
Standard Test Method for Determining the Peak Force-to-Actuate a Mechanical Pump Dispenser
SCOPE
1.1 This test method covers the determination of the peak force-to-actuate, sometimes called force-to-actuate (FTA), of a mechanical pump dispenser.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine in the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 5.

9.4 If the test is to be performed on an unprimed mechanical
pump dispenser, place the mechanical pump dispenser onto the
holding fixture while directing the exit orifice of the mechani-
cal pump dispenser away from the direction of the operator. If
the test is to be performed on a primed mechanical pump
dispenser, and the mechanical pump dispenser has not been
primed, prime the mechanical pump dispenser in accordance
with Test Method D 3890.
NOTE 4—A product collection device or means of ventilation is
recommended for the safety of the operator.
9.5 Activate the force–to-actuate tester to determine the
initial contact point between the plunger of this device and the
actuator of the mechanical pump dispenser.
NOTE 5—If the ram is allowed to bottom-out on the package, this may
result in an excessive peak force value, a damaged package, or damaged
machine, or combination thereof. Bottoming-out of the ram is detected by
watching the force gage for a spike at the end of the travel. If the ram on
the tester does bottom-out, the peak force value will be much greater than
the actual peak force to actuate. The true peak force to actuate should be
recorded as the value at the base of the spike. This value may be seen on
the force curve generated.
9.6 Activate the force-to-actuate tester.
9.7 If the force-to-actuate tester does not automatically
calculate the peak force to actuate, the operator must determine
the peak force
